- 01 Unmatched Dynamic Range
- 02 Highest Resolution
- 03 True Displacement Control
Micro-Electro-Mechanical System (MEMS)-based force sensors have an unmatched dynamic range of up to 100 kHz, thanks to their exceptionally small mobile mass and high stiffness. Moreover, the fine fabrication tolerances of MEMS achieve the lowest possible noise floor, reaching down to 500 pN.

A key quality metric of a nanoindenter is its ability to accurately measure indentation depth. This is limited by the noise floor (resolution) of the displacement sensor. With an unmatched noise floor of <50 pm, the FT-I04 Femto-Indenter achieves excellent results even at the most shallow depths, as shown here with repeatable indentation curves to only 5 nm on quartz glass.

Testing modes
Nanoindentation
Nanoindentation assesses the local mechanical behavior of a material by pressing a sharp tip into its surface and measuring the force needed to create an indent. This technique measures local mechanical properties (including hardness, elastic modulus, strain rate sensitivity, and others) directly from the material's response.

Mechanical Microscopy
Nanoindentation mapping, or mechanical microscopy, employs a nanoindenter in a microscope-like manner. It enables the mapping of mechanical properties of intricate microstructures in minutes, thanks to the integration of rapid indentation speeds and precise spatial resolution.

Strain-Rate Control
Time, like temperature, is a key parameter for materials deformation. Speed determines the active deformation mechanism. Strain-rate control during testing achieves the most consistent results and allows exploring the material's response from creep to impact, even within a single indent.

High-Temperature Testing
Temperature changes the mechanical behavior of materials. It is crucial for assessing operando mechanical properties, under conditions close to their target application. Using precision MEMS heating to achieve rapid temperature matching and thermal control, stable measurements can be performed even at high temperatures.
